The information, as provided, is for informational purposes only and should not be
interpreted as complete, nor should it be considered legally binding. Coordination with both
your state and the destination state plant regulatory agency listed above may be necessary to
stay up-to-date on revised requirements.

NURSERY STOCK DEFINITION

Nursery stock: Hardy, cultivated or wild woody plants, such as trees, evergreens, shrubs and vines,
and small fruits such as strawberries and raspberries. (Note: this last part is interpreted to mean that
small fruit plants - not the fruits - are the regulated entities.)

GENERAL SHIPPING REQUIREMENTS

Any nursery stock shipped into Iowa must have attached, either to the plants or to the package
containing the plants, a tag or label showing the nature and quantity of the contents, the locality
where they were grown, and the name and addresses of both shipper and receiver. Also required,
either on or accompanying the shipment, is a certificate of inspection from the plant regulatory
official of the shipping state, territory, district, or country stating the articles have been inspected
and found free from plant pests. Woody plants originating from areas under quarantine for the
gypsy moth must be accompanied by a certificate or federal stamp stating that the stock is free
from gypsy moth infestation. Iowa abides by the requirements outlined in the NPB Japanese Beetle
Harmonization Plan. And all firewood must be labeled with the County and State of harvest origin.
